The 3889124 is specifically for G, GF, H, and HF-generation engines — other 4.3L, 5.0L, and 5.7L variants use different belts (see 3860086 and 3586326 for other configurations). Checking the engine model suffix and confirming against the maintenance diagram is the fastest way to get the right belt. When the belt is being replaced, it’s also worth checking the tensioner — a belt that has been squealing or walking off a pulley is often a tensioner problem, not just a worn belt.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564037799972,"sku":"3889124","price":83.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/8aae419d-d34b-4de3-87ec-0c2577205f99.png?v=1788845222","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-serpentine-drive-belt-3889124","provider":"Marisol Marine Company","version":"1.0","type":"link"}
